چکیده
|
In this article, the authors introduce two new subclasses of a class m-fold symmetric biunivalent functions in open unit disk. coefficient bounds for the taylor-maclaurin coefficients |am+1| and |a2m+1| are obtained. furthermore, we solve ”fekete-szego functional problems for functions in f∑ ,m(γ, µ, ϑ) and m∑ ,m(κ, η, ϑ). also, several certain special improver results for the associated classes are presented.
